.REFRIGERATING-ROOM.

SPECIFICATION forming part of Letters Patent No. 256,052, dated Aprili'4, 1882.

- Applica-non inea october 6,1880. (Nomerie.)

To all lwhom it may concern:

Be it known that I, HENRY A. ROBERTS, of Detroit, in the county of Wayne and State of Michigan, have invented a new and useful Improvement in Refrigerating-Rooms, of which the following is a specitication.

My invention relates chiefly to the construction of rooms on hoard ships for the purpose of transporting fresh meats and other perishable articles, wherebyeconomy of space is secured, and at the same time the articles are transported without danger of loss; and itconsists, rst, in a chamber situated between the decks of the vessel and divided into vertical preserving-compartments having icereceptacles, and into vertical compartments for the storage ofthe surplus ce'adjoining the preserving-compartments, all of such apartments being disconnected and having independent doors; and, second, in the combination ofthe same parts with the ice-receptacle constructed to open into the ice-storage compartments, all as hereinafter explained. This method of construction tends to keep the outside of the preserving chambers cool, and also facilitates the charging of the ice-receptacles.

In the drawings, Figure lis a top view of my improved refrigerating-room on the line of the rack or iioor of the ice-receptacle, and Fig. 2 is a vertical section of the same.

A represents one deck of a ship, and B represents another deck, and between these two decks myrefrigerating-room O is built in any suitable manner.

D is a compartment or preserving-chamber within this room, having an ice-receptacle, H, which may be of any desired form or material.

F is a door for aii'ording access to the preserving-chamber D.

E is a'compartment for the storage of ice, adjoining the preserving-chamber D, but divided from it by the partition J. A door, I, in partition J affords access from compartment E to ice-receptacle H, and closes all connection between compartment E and preservingchamber D.

Gis a hatch or door for admitting entrance to compartment E.

The surplus ice is stored in compartment E, and the ice-receptacle H can be charged when necessary by opening the door I. If the icereceptacle he a tight metal box, it should l.

have a funnel or neck opening through the partition J at the top of the box, and closed bya stopper. The doorIshould be kept closed, except when opened for charging the ice-receptacle H.

If the room O should be too large to be divided into one refrigerating-compartment and partment (one or more) of a refrigerator and a receptacle (one or more) for the refrigerant, acompartment (one'or more) for the storage of surplus ice, arranged with relation to each other substantially as described.

2. An inclosed chamber divided into verti cal preserving or refrigerating compartments having receptacles for the ice or other refrigerant, and vertical ice-storage compartments ad. joining such preserving-compartments, all of such compartments being disconnected and havingindependent doors, substantially as and for the purpose set forth. v

3. In combination, vertical preserving-compartments, vertical compartments for the storage of surplus ice adjoining such preservingcompartments and not connected therewith, and receptacles for the refrigerant openinginto` such storage-compartment`s, substantially as described and shown.
